We are attempting to plan a road trip with two adults and three kids (ages 5,7,8) in a minivan. We would like to go from Florida to Mt. Rusmore,Yellowstone,Washington state,Oregon,Yosemite,Grand Canyon,and back home to Florida. From the Grand Canyon to Florida we are open to other stops. We have roughly a month to complete the trip and would like if possible to keep lodging expenses to no more than 100/day. In a couple of locations(Wa,Oregon,and AZ) we can stay with family and friends. For the rest we were thinking maybe KOA campgrounds or low budget hotels. Please throw tips,suggested attractions,and lodging tips our way. Food if possible we'd like to limit on the road purchases and eat more picnic style. There will be one driver age 30 and the other adult about age 60 along for the ride. Not sure what other info to post.
